- $36 it known that I, Ronnn'r A. 'Bnoons, a citizen of the United States, and a resident ofthe city 'of Chicago, in the county of Cook and State of Illinois, have invented a certainfnew and useful Improvement in Surface Discharge Apparatus for Tanks; andI do hereby declare that the. following 18 a full, clear, and exact description of the same, reference being had .to the accompanying drawings, and to the letters of reference marked thereon, which form a part -of this specification. 'lt .hasibeen a source :of .much difiiculty and e?bense on the partof the users of the ile and other vehicles and devices driven b p fuel in passing from the tank orreceptaole contammg the same, 'thro h the v smm particles of dir 9 even small quantities of water which in the one case clogs up the car- .hureter and in the other prevents the. flow .of the hydro-carbon. fuel therethrough and causes the engine or motor to operate irregularly 'or not at all. Various devices, some of which arequite'e ensive and com licated, have been devised t dr the purpose 0 removpartlcles from the gasolene between the tank and carbureten, .N one have, however, proven very sucpessful and frequently complications brought into the construction and the various more or less complicated valves employed have n a source of as great annoyance as the I occasional stoppage of the carbureter from the causes above mentioned. Although great. care is usually employed to prevent water the tank with the gasolene, it nevertheless frequently happens, and,

' once J11 the tank, it inev1tably acts to disturb the operation of the carburetor, no satisfactory 'means having been heretofore devised to remove the water in its passage from "the tank to the carbureter.

The object of this invention is to provide means within the tank for feeding the gasolene'or other hydro-carbon vapor from near.

thesurfaceof the contained fluid in the tank to the carhureter, thereby permitting any water contained in the tank to remain undisturbed at the bottom, from whence it may be drained ofi, if desired.

It is also an object of the invention -to afford in a device of the class described an mtake pipe, which is adapted to be self- 'lpocmcattgniot Letters rams Application flea September 2, 1309. can No. slam.

adjust Pivith reierence to the'liquid in the ktd dr tan aw only from near the top thereof and to afiord in such a tank a bottom recess or chamber adapted to collect all the dirt, water, or other material or ingredients in the gasolene or hydro-carbon and to permit the same to be'discharged quickly from the tank without the possibility of the loss of finyd considerable quantity of hydro-carbon It is also an object of the invention to afford a discharge pipe within the gasolene supply tank for explosive motors, the intake end of-which is provided with a float ,to render the same self-adjusting in the tank with reference to the surface of the fluid.

con ained a Theinv iition consists in thematters hereinafter described d more fully pointed out and defined in the iap nded claims.

In the drawings: I igure 1- s a side elevation partly'broken away of a gasolene tank containing mechanismz embodying my invention. Fig. 2' "is a similarview showing the tank practically empty. Fig. 3 is a section on line 3-'3 of 1. Fi 4c is a sectionon line 44 of 'Fi '2. 5 is an enlarged detail section. 0 the col ectin recess and the discharge valve therefor. i '6 is an enlarged sectional detail illustrating the pivotal engagement of the discharge pipe with the'pipe eading to the carbureter. Fig. 7 is a section on line 77 of Fig. 6. Fig. 8 is an enlarged transverse section of the float and screen head for the discharge pipe. Fig. 9 is a face view thereof. Fig. 10 1s a view similar to Fig. 9, but with the screen removed.

As shown in the drawings: A, indicates a gasolene or hydro-carbon tank of any kind or construction, which, in the construction shown is cylindrical. Near one end of the tank onthe lower side thereof is a receptacle or chamber a, of small size, which communicates in the tank and is rovided with a drip or vent cook a', to disc arge its contents. Said receptacle, as shown, is concave and affords connection with e. pim 5. leadintegral ing to the carbureter. At the inner end of said sleeve is bored to receive a tube or pipe C, and at the inner extremity of said sleeve is bored to a larger size to receivepacking c, against which fits a shoulder a, on said pipe G.

Threaded into the side of the sleeve 13, near its inner end is a set screw 0 which may be provided with a jam nut 0 to hold the same in adjusted position, and the end of which extends through a peripheral slot 0 in the tube 0, to hold the same from longitudinal movement in said sleeve, though permitting free rotation of said pipe or tube 5 C, in said sleeve.

Threaded into the side of the .pipe C, and' near the inner closed end thereof, is a metal tube D, which extendsupwardly from said receptacle into the tank and is there bent, as shown in Figs. 1 and 2, to permit the inner end of the pipe to lie flat within the tank when the tank is empty, and is of a length when the tank is filled to enable the inner' end of the pipe to extend to near the top of the tank.

On the inner end of the pipe D, is secured a combined screen and float D, which, as shown, is constructed of metal and com-; prises a hemi-spherical shell into one side of.

which extends said pipe D, and which is divided by a partition 03, into a rear closed= chamber affording the floatj On the front; or open side of the shell is an upwardly projecting partition d, extending for, nearly. as half the width of said open side and secured on said open face in said partition (1', is a fine screen at, preferably of copper wire gauze. In the bottom of the tank at a point coinciding with the position of the float and 40 screen head D, when the tank is empty is' a recess a, adapted to permit the screen to fall therein to insure the thorough emptying of the tankand its hydro-carbon contents.

Conveniently, the bottom of said recess at its middle point is in alinement wlth the bottom of the tank thereby permitting the recess to drain readily to the receptacle a, thus preventing any accumulation of water or sediment in said recess.

The operation is as follows: Whenthe tank is filled withgasolene, the float raises the intake end of the pipe D, to bring the screen thereon to the surface of the liquid in the tank. \Vater and sediment being heavier, sink to the bottom of the tank and eventually to the receptacle a. As the gasolene or other hydro-carbon is consumed the intake end of thepipe gradually descends at all times being positioned to take the liq uid from, at, or near the surface of the tank. hen the tank is emptied. the screen face at the intake end of the discharge pipe drops into the recess as, in the bottom of the tank, thus removing the gasolcnc or other hydrocarbon to the last drop except from the are possible without departing from. the

small receptacle (1, extending below the tank.

In this the water and sediment has accumulated (should any be present) and if, before refilling the tank,'the vent or dripcock be opened, all such material may be discharged and practically without loss of gasolene, inasmuch as the mole tacle'a, may be very small relatively to tlie size of the tank, the proportions shown in the drawings being somewhat exaggerated for the purpose of clearne'ss of. illustratio The operation is wholly automatic and gositive, and, owing to the extremely simple construct-ion, does not add greatly to the; expense as compared with tanks as at presentlconstructed. so Nu erous details o'fthe' cdnst'rilctioii 'may,

- of course, be varied, as, for instance, for con- -venience a .tap or plug a,-m ay be inserted in the side ofthe receptacle a, in alinement with .the sleeve B, to facilitateassembling s5 and also to afford access tothe interioriof the receptacle, should it ever be desired. 1

.I have shown but one of several constructions embodying my invention; Itherefore do not purpose limiting this application forpatent otherwise than necessitated by the prior art,- as obviously manyvariation's from the particular construction and form shown principles of this invention.

I claim a l. The combination with a tank of an outlet pipe therefor ivoted thereinand a shell on the intake end of said pipe compris 1 ingan air tight chamber or float and an intake chamberwith which said pipe communicates, said floatadapted to support said intake chamber at approximately the surface of the liquid in the tank.

3. A tank, a receptacle connected in the bottom-thereof a. discharge pipe pivotally connected above'the bottom of said"recep tacle, a float ontheintake end of said pipe extending beyond the end thereof and provided with a chamber with which the intake pipe communicates and a screen affording 1 the outer wall of said chamber.
